Significant FPS Drop When Running Multiple train_smac Instances

[meifannao]

Hello,

I noticed an issue where the FPS drops significantly when running multiple instances of train_smac.

When running a single instance, the FPS reaches 400+.
However, when running multiple train_smac instances simultaneously, the FPS drops to around 100 for each instance.
The server resources should not be a limitation:

CPU and memory usage remain below 30%.
GPU utilization is mostly at 0%.
Could you please help me understand why this is happening and suggest any possible solutions?

Thank you for your support!
